Competitive alternative Frederikshavn Forsyning, the local district heating company, and MAN Diesel & Turbo in Frederikshavn go hand in hand to meet the needs of locals and businesses in Frederikshavn Municipality regarding heating and hot water. District heating is an environmentally friendly solution, and a competitive alternative to other types of heating, which always makes it the best heating choice where possible. Skagen District Heating Company – also situated in the northern part of Denmark - has 2600 customers and sells 60,000 MWh heating and 18,000 MWh electrical power annually. The heating is a mix of 65% production and 35% surplus heating from the fishing industry. The heating production consists of three gas engines, which produce 14 MW electrical power a day and 21 MW heating a day. An electrical boiler produces 10MW a day, and four gas boilers produce 46 MW a day. The surplus heating from the fishing industry comes in the form of hot water with a temperature varying from 65 to 75 degrees. The fishing industry delivers up to eight MWh varying according to their production level and season. Their contribution is high between December and mid-June, which fits well with the customers’ heating demand.
The price of the heating is charged via fixed payment on account. It is regulated annually and if the customers have paid too much, the extra amount of money is transferred to the payment on account the following year. In addition, the three large engines are supplied with natural gas. Heat pumps cool the exhaust gas to 28 degrees. The result is a very high efficiency. “When it is windy, the wind turbines spin and the electricity prices go down. This gives us the opportunity to use the power in our electric boiler. Thus the power generated by the wind turbines is transformed to heat”, says Jan Diget, CEO of Skagen District Heating Company.

Are you ready for the shift towards a more energy efficient heat supply? You cannot optimise what you do not measure
Flow from fishing industry and low fees
The shift towards renewables requires intelligent and integrated energy systems, and district heating plays a key role in this development. So far, the production has been determined by the consumption, but in future, the consumption will have to adapt to the fluctuating production based on renewables. This calls for you to be more flexible and to run the network closer to the limits, making it even more crucial to continuously manage and optimise your production decisions and distribution network. For this you will need the full transparency you can get from frequent and accurate meter readings. Learn more at kamstrup.com/heatsupply
